HORACE IV. CLARK. OFJVIAITOON, ILLINOIS.

To all 'whom fit may concern.

Be it known that I. Hormon W. (linnn,

a citizen otl the United States, residing at Matteoli, county of (foies, and State ot,`llli Specification-of Letters Patent. Application filed January 16, 1911.

nols, have invented certain new and usetul Improvements iu Pipe-Couplings, of which the followingl is a true specification, reiference being A,had to the aecomjninying 'drawings.

My invent-ion is an improvement in couplings where one member is obliged to bear the Weightof the other member such as 1s oft times employed in coupling water meters and the like onto service pipes where the Weight of the meter must rest on the pipes.

In the drawings, Figure 1 'represents a water meter attached to -a service pipe by the use of my coupling. Fig. 2 is a plan view of coupling. F ig. 3 is a sectional elevation of the same. Figs. 4 and 5 are details of modifications of my invention.

More particularly described, M represents a meter'car'rying spuds m fm, designed to form one member ot the joint to be coupled. m m are exteriorly threaded at their outer ends and present coupling faces m m on which by preference I make smooth faces. I provide a frame A rectangular in form carryingatoneendashelf or bracket d? and at its other end an interiorly threaded collar a designed to engagethe threaded end of the spuds '111, m. Engaging the frame A at the end opposite to the Spud m is a screw o passing laterally through a suitable aperture in the frame A having on its outer end a Wheel a Jfor operative purposes.

To the service pipe C is attached by threaded 'connection an elbow joint B the free end of which is adapted to engage the end of the spud wz. At this free end of the joint B I provide concentric annular ridges o which are so constructed as to conform to the unevennesses of the surface ot the end of thespud lml under pressure and thereby forming a tight joint without the use of a gasket.. Ilowever, this is a preference and any Jform of gasket or packing which will insure a tight joint may be utilized..- The side faces of the joint B are squared shown in Fig. 2A and a shelf b 1s struck out at right angles trom the face of the joint B and adapted to form a support for the meter M by engagement with the frame A at the point a2.

In operation, with the screw a in a retired position in the trame A, the meter M ,the t'rameA and the coupling is eti Patented Jan. 30, 'L91 2. Serial No. 603.025.

is placed in position by dropping the .frame A upon the joint I and engaging the said trame with the shelf Z thus bringing the .tree end of the joint B in opposition to the outer end ot' the spnd mf. Then by rotation ot the wheel n, the screw a.' drives the joint B andthe spud m. .into binding'contact with each other. The apertures ai* L4 in b2 in the shelf I) are deeaeh with the other'when leted and permit the pas sage of a sealing wire through ther two members.

In Figs. 4: and 5, I illustrate a moditication ot my device. D is a collar threaded interim-ly throughout part of its width for the purpose of engaging the end of the Spud m. Near the tree end of the joint. B is provided agroove (Z4 running'around the entire circumference of the joint B and parallel with the t'ace of the free end thereof. Ihrough the collar D are passed screws (Z2 (Z2 winch engage loosel the groove d4. Recesses da [Z8 are provi ed in the outer tace of the collar D. By the use of a Wrench inserted in the apertures (Z3 d? the collar D may be moved along the end of the spud m signed to register and by its engagement with the joint B i draw the same into Contact with the spud m and form a coupling. By this method We can draw the joint'. B into contact with the spud in, instead oi driving it into contact as heretofore descril'ied.

vil have here described but one coupling and I would have it understood that I utilize'two similar couplings applied to the 0pposite sides of the meter M atthe spuds m m., one ot' which is intended for an intake and the other for an outlet.

What fl claim as my invention is 1. In pipe couplings the combination with a. pipo member, a trame rigidly secured near the iyee end of said pipe member and extending beyond the said end, ot' another pipe member carrying a shelt near its free end, the said frame of the said first named )i )e member bein desirned to rest luion the said shelf ot the second named pipe member in suoli manner as to permit and maintain the register of the free ends ot said pipe members and means for forcing the said pipe members into binding contact with each other.

In a pipe coupling the combination with a pipe member, a frame rigidly attached near the free end thereof and propipe membee in regsieifa end ineens for` forcing the seid pipe membe'e im@ bmng Contact' with eeen einem eenes'ng ef/ e screw passing ,latere-Hy through ehe seid frame and engaging the seid shelf bearing pipe member. n e .'plpe eoupllng the eemblnatlon `L wlth a. plpe membe and a frame lgldy etacked 'tewhe free end thereof and projectlng beyond the sind :nee en, o" another 1'5 lpipe member provided neer its end with an 3 w lame-snee elbow, e sneu mieu upon the unter fece of the sald elbow wlneh' shelf is deslgned 'to receive the said frame of the first named pipe member and beer the Welght thereof and to hom the sald plpe members 1n regletel with enen other, end a scyew passing laternly through the seid frame andfadepted to engage the Sind shelf benl-mg plpe member whereby the sind pipe members may be g driven info binding Contact with each other. v25
